Methods

staticCesium.GeoArcGISTiledElevationTerrainProvider.getInstanceByCapabilities(options) → Promise

通过请求服务元信息创建GeoArcGISTiledElevationTerrainProvider
Name Type Description
options Object 参数选项：
Name Type Description
viewer Viewer optional 三维球对象
url Resource | String 地形服务地址
parameters Object optional 传递给服务的附加参数
Returns:
如果请求元信息成功，则创建Provider
Example:
var promise = Cesium.GeoArcGISTiledElevationTerrainProvider.getInstanceByCapabilities({
 url: 'https://192.168.100.231:6443/arcgis/rest/services/Dem/ganjiang/ImageServer'
});
promise.then(function(terrainProvider) {
 viewer.terrainProvider = terrainProvider;
});
